CLEFIA

CLEFIA is a proprietary block cipher algorithm, developed by Sony. Its name is derived from the French word clef, meaning "key". The block size is 128-bits, and the key size can be 128-bit, 192-bit or 256-bits. It is intended to be used in DRM systems. It is among the cryptographic techniques recommended candidate for Japanese government use by CRYPTREC…
